HI-8382, HI-8383

The HI-8382 and HI-8383 bus interface products are silicon

gate CMOS devices designed as a line driver in accordance

with the ARINC 429 bus specifications.

Inputs are provided for clocking and synchronization. These

signals are AND'd with the DATA inputs to enhance system

performance and allow the HI-8382 to be used in a variety of

applications. Both logic and synchronization inputs feature

built-in 2,000V minimum ESD input protection as well as TTL

and CMOS compatibility.

The differential outputs of the HI-8382 are independently

programmable to either the high speed or low speed ARINC

429 output rise and fall time specifications through the use of

two external capacitors. The output voltage swing is also

adjustable by the application of an external voltage to the VREF

input. The HI-8382 has on-chip Zener diodes in series with a

fuse to each differential output protecting the ARINC bus from

an overvoltage failure. The outputs each have a series

resistance of 37.5 ohms. The HI-8383 is identical to the HI-

8382 except that the series resistors are 13 ohms and the

overvoltage protection circuitry has been eliminated.

The updated HI-318X and HI-8585 ARINC 429 line drivers are

recommended for all new designs where logic signals must be

converted to ARINC 429 levels such as a user ASIC, the

HI-3282 or HI-8282A ARINC 429 Serial Transmitter/Dual

Receiver, the HI-6010 ARINC 429 Transmitter/Receiver or the

HI-8783 ARINC interface device. Holt products are readily

available for both industrial and military applications. Please
